Types of pultruded advanced composites

Pultruded advanced composites used in civil engineering applications are manufactured in three basic structural shapes (Bakis et al., 2000 Hollaway, 2010)

Although the above shapes are used in the majority of structural applications of GFRP profiles, these first-generation shapes have several disadvantages that are essentially related to their sensitivity to impact and their stability
